CLEANING AND STERILIZATION

The screen in the pneumotach mouthpiece should be visually
inspected before each use.
If sputum or other foreign matter becomes lodged in the screen, it
can cause erroneous readings. To clean the screen, remove the
mouthpiece and scrub it with a small brush. Then check calibration
(see p. 31).
The pneumotach assembly should be removed (see p. 39), cleaned
and sterilized prior to any maneuvers involving inhalation, such as
MVV.
Routine maintenance of the pneumotach assembly should include
cleaning and sterilization after every 50 maneuvers.

zation by any of the following methods:
Steam Autoclave (270" F, 27 PSI, 6 min cycle)
